Mont Royal Moselle Valley

Above Traben are the remains of the vast Mont Royal fortress, constructed between 1687 and 1698 and designed by Vauban for Louis XIV as a base from which to project French power. Ruinously expensive, it was dismantled before completion by the French themselves under the Treaty of Ryswick. The 1.5km-long footpath up to the site begins at the upper end of Römerstrasse.
